Steven M Elk Grove , CA February 25, 2017 Appliance: General Electric Refrigerator PFSS6PKXDSS Ge Refrigerator Pfss6pkxdss: Clogged drain ice build up in the fridge model# pfss6pkxdss. How to replace Asm Cover-Evap Ref. I replaced the back cover because it was broken because the ice split the Styrofoam ducting, spent about five hour thawing out the drain. I used boiling water and used compressed air to blow out the liquid. GE really dropped the ball on this model!! I added a copper wire from the defrost heater down the drain. To keep the drain open. The panel just snaps in but don't force it!! 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
